If these lights are on in your car, don’t turn them on, otherwise the consequences will be serious.
Normally, after the key is turned to the third gear, when the fault light on the dashboard is turned on and goes out in turn, the vehicle will self-check. If the fault light is still on after the car starts, or if the fault light suddenly turns on while driving, it means that the engine is faulty and must be stopped and checked.
1.Water temperature warning light
The water temperature alarm is on, indicating that the temperature of the engine may be very high or there is no water. The normal working water temperature of the engine is mostly around 90 ° C. The high temperature will cause great damage to the engine, or even damage it, and the cylinder will appear directly. So the water temperature alarm is on. Be sure to stop and check to see if the antifreeze is insufficient, or if there is any water leakage, depending on the normal operation of the electric fan.
2.Engine fault light
- Not scheduled for maintenance
Insufficient combustion The combustion condition of the engine is not good - Engine knocking The engine has a special knock sensor to monitor engine knock. Engine knock has meant that it may cause severe engine parts damage or severe power loss. Generally, knocking is divided into sensible knocking and non-sensing knocking. In the case of non-sensing knocking, the engine computer will adjust the engine control parameters according to the monitored conditions to avoid greater adverse effects, When the non-sensing knock has exceeded the range that the engine computer can adjust, the engine fault light will also light up and alarm.
- When the cold car is started, especially when the weather temperature drops sharply, the pollution light will be turned on due to the temperature correction problem of the computer, but it will be relatively stable as long as the temperature drops to a certain temperature without fluctuations. Internal Causes of Engine Fault Light
- Fuel quality is not good
- There is also a special case where the engine light flickers, and the reason for the flicker is generally lack of cylinder; the reason for lack of cylinder is that the spark plug is not working or the fuel injection nozzle is blocked and the ignition coil is not working.
When the engine fault light is on, there are the following reasons:
3.Oil pressure lamp
The oil pressure lamp lights up, indicating that the engine oil is low, the engine oil is seriously insufficient, the lubrication is insufficient, and the engine is easy to pull. Therefore, it is necessary to check whether the vehicle is leaking oil or whether there is fuel phenomenon, and refuel in time.
4.Brake system failure indicator
The brake system fault indicator is on, indicating a problem with your brake pads or brake fluid. This is the time when the brake system should check for oil leaks or the brake pads are not replaced. This must be brought to our attention, because the brakes are likely to fail, and the consequences are unimaginable.
5.Airbag fault light
It is also relatively common for airbag fault lights to light up. If it is on, it must be checked and repaired in time.
Therefore, we must pay attention to these fault lights when we drive. Once they start to light up, we must find professional maintenance personnel to deal with them, otherwise the consequences are unimaginable.
